2.2 Measured parameters
测量参数
The HP21 measures relative humidity with a ROTRONIC Hygromer® IN1 capacitive sensor and
temperature with a Pt100 RTD.
HP21 用ROTRONIC Hygromer® IN1湿敏电容测量相对湿度，用Pt100 RTD测量温度。
2.3 Calculated parameters
计算参数
Using the ROTRONIC HW4 software, the HP21 can be configured by the user to calculate either the dew
point or the frost point.
通过HW4软件，用户可以使用HP21计算露点或霜点。
2.4 Sensor protection (dust filter)
传感器保护（防尘过滤器）
The HP21 is supplied with a Polyethylene filter to protect the sensors against dust particles and high air velocity.
HP21 自带聚乙烯过滤器，保护传感器免受粉尘颗粒物或高风速的影响。
2.5 Service connector
维护接口
The service connector is a UART digital interface (Universal Asynchronous Receiver Transmitter) with a
mini-USB type connector. This allows connecting the HP21 either to a PC running the ROTRONIC HW4
software or to a probe input of another instrument that is compatible with the HygroClip 2 (HC2) probes.
In both cases a service cable is required. See “Maintenance” for the location of the service connector and
for the type of service cable to be used.
维护接口是一个UART数字接口（通用异步收发器）有一个微型USB连接器。这种接口可使HP21与运行HW4
软件的电脑连接或与另一个设备（与HC2探头兼容）的探头输入连接。这两种情况下都需要维护电缆。见
“维护”维护电缆的连接位置及适用类型。
Connecting the HP21 to a PC is used to configure the HP21, gain access to the HP21 functions such as
humidity and temperature adjustment, read data from the HP21 on the PC and update the AirChip 3000
firmware.
HP21与电脑相连接，可对HP21进行功能设置，可进入HP21功能选项，例如温湿度调节，通过电脑读取
HP21数据和升级AirChip 3000固件。
Connecting the HP21 to another instrument is useful only when the other instrument has its own display
and keypad, and has a more powerful internal menu than the HP21 (example HP23 hand-held calibrator).
This allows showing the data measured by the HP21 on the other instrument display and also allows
using the other instrument internal menu to do for example a humidity and temperature adjustment of the
HP21.
HP21与另一个设备相连，该设备带显示和键盘，并且内部菜单功能比HP21强大（例如HP23手持表）。可
以通过该设备显示HP22的测量结果并可以通过该设备内部菜单选项对HP21做温湿度调节等。

Widron Measurement And Control Co., Ltd.Tel:400 883 6696 Fax:020-82316696 Page 12 of 21
4.7 Practical advice for measuring humidity
湿度测量实用指导
The most common source of error when measuring relative humidity is a difference between the
temperature of the probe and the temperature of the environment. At a humidity condition of 50 %RH, a
temperature difference of 1C (1.8 F) typically results in an error of 3 %RH on relative humidity.
测量相对湿度时最常出现的误差来自探头温度与环境温度的不同。在湿度环境为50%RH，温度相差1℃，
导致相对湿度3%RH的误差。
When using the HP21 hand-held indicator, it is good practice to monitor the display for temperature
stability. The probe should be given sufficient time to equilibrate with the environment to be measured.
The larger the initial temperature difference between the probe and the environment to be measured, the
more time temperature equilibration requires.
当使用HP21手持表测量，它能很好的控制温度平衡。应给探头足够长时间与被测环境相平衡。当探头与
被测环境温差越大，所需要的平衡时间就越长。
In extreme situations, condensation may occur on the sensors when the probe is colder than the
environment. As long as the humidity / temperature limits of the humidity sensor are not exceeded,
condensation does not alter the calibration of the sensor. However, the sensor has to dry out before it
can provide a valid measurement.
在恶劣环境中，当探头比环境温度低时会在传感器上形成凝露。只要温湿度值不超过湿度传感器的测量范
围，凝露不会影响传感器的校准。尽管如此，为了得到有效测量结果应该在测量之前，擦干传感器。
Non-moving air is an excellent insulator. When there is no air movement, surprising differences in
temperature and humidity can noted over short distances. Air movement at the probe generally results in
measurements that are both faster and more accurate.
不动的空气是一种极好的绝缘体。没有气流，即使在相距很短距离是所测得的温湿度都相差很多。探头周
围的空气流动速度会影响测量结果，通常是风速更快，测量更准确。
5 Maintenance 维护
5.1 Service cable 维护电缆
Cable AC3006 converts UART (service connector) to USB and is used to connect the HP21 to a USB
port of a PC running the ROTRONIC HW4 software. Prior to using this cable, the ROTRONIC USB driver
must be installed on the PC. Both the driver and the installation instructions (document
E-M-HW4v2-Main) are located on the HW4 CD.
AC3006电缆将UART（维护接口）转为通用串行总线，用于连接HP21，和运行HW4软件的电脑。在使用
该电缆之前，电脑上应先安装USB驱动。
As an alternative, cable AC2001 is used to connect the HP21 to a probe input of the HP23 hand-held
calibrator. For service purposes, the HP23 offers essentially the same functionality as the HW4 software.
作为选择电缆AC2001是用于连接HP21和HP23的一个探头输入端。以辅助为目的，HP23提供和HW4软件
相同的功能。
5.2 Location of the service connector (mini USB type)
维护接口位置（微型 USB 类型）
Widron Measurement And Control Co., Ltd.Tel:400 883 6696 Fax:020-82316696 Page 13 of 21
WARNING: the service connector is a UART interface with a mini-USB connector type. Do not connect
the service connector directly to the USB port of a PC or hub.
The service connector (UART interface) can be accessed without opening the enclosure after removing
the protective red round cover.
警告：维护接口是一端 UART 接口带微型 USB 接口。不要直接将维护接口连接到电脑 USB 口或 hub 口。
该维护接口（UART 接口）无需打开外壳，只需打开红色保护罩连接。
5.3 Periodic calibration check 周期性校准检查
Both the Pt 100 RTD temperature sensor and associated electronics are very stable and should not
require any calibration after the initial factory adjustment.
Pt 100 RTD温度传感器和绝缘电路都非常稳定，在出厂后无需做任何校准。
Long term stability of the ROTRONIC Hygromer humidity sensor is typically better than 1 %RH per year.
For maximum accuracy, calibration of the HP21 should be verified every 6 to 12 months. Applications
where the HP21 is exposed to significant pollution may require more frequent verifications.
ROTRONIC Hygromer 湿度传感器的长期稳定性是典型的漂移1 %RH/年。为了达到测量精度最好，HP21
应该每隔6到12个月校准一次。如果应用在暴露的环境，并有重大污染，则要求经常做校准。
a)
Procedure for adjusting the HP21 from the keypad通过键盘调节HP21的过程
The keypad of the HP21 allows a 1-point adjustment of temperature or humidity against a reference. A
1-point adjustment has the effect of adding the same offset to all measured values. A multi-point
adjustment is not possible from the keypad and requires using either a PC with the HW4 software
installed or the HP23 hand-held calibrator.
HP21键盘可以做单点温度调节或湿度参考点的设置。单点迁移节会影响整个测量范围偏移量。多点校准
不能通过键盘进行，而需使用装有HW4软件的电脑或HP23手持表。
When the parameter to be adjusted is stable, press the MENU key to show the internal menu on the
display
当参数被调节稳定，按菜单键可以显示。
Use the DOWN key to select either H-Adjust or T-Adjust and press the ENTER key
使用向下键选择湿度调节或是温度调节，然后按回车键确认
Make sure that the text line beginning with RefValue is highlighted and press the ENTER key
保证在参考值为高亮状态然后按下回车键
Widron Measurement And Control Co., Ltd.Tel:400 883 6696 Fax:020-82316696 Page 14 of 21
Use the UP or DOWN key to change the reference value as desired
使用上，下键更改参考值直到你想要的
Use the DOWN key to highlight the Adjust text line and press the ENTER key
使用向下键到调节菜单为高亮状态时，按回车键
The HP21 confirms the adjustment with the message “Adjust OK”
当HP21显示信息“Adjust OK”表明调节 确认完成
Press the MENU key twice to exit the menu and return the HP21 to normal operation
按菜单键两次跳出菜单，并返回到HP21初始操作界面。
Notes:
o The calibration point is automatically deleted from the probe memory after an adjustment
o Instructions for using the ROTRONIC calibration devices and humidity standards are provided in
document E-M-CalBasics
o Because the HP21 has no real time clock, the date of the adjustment is not written to the HP21. If
retaining the adjustment date is important, use the HW4 software to adjust the HP21.
注明：
o校准点在调整后自动从探头存储器中被删除
o关于使用ROTRONIC校准设备及湿度标准说明见文件E-M-CalBasics
o由于HP21没有真正的时钟，调节的数据不能保存到探头。如果有必要保存调节数据，应使用HW4软件进
行探头的调节。
b) Procedure for adjusting the HP21 with the ROTRONIC HW4 software:
使用HW4软件调节HP21的过程：
Use cable AC3006 to connect the service connector of the HP21 to the USB port of a PC with the

5.5 Cleaning or replacing the dust filter 清理或更换过防尘过滤器
Depending on the application, the dust filter may require cleaning from time to time, Cleaning should be
done without removing the filter from the probe. Clean the filter with a fine brush. If this is not sufficient,
the filter should be replaced. To do this, unscrew the filter from the probe. Before putting on a new dust
filter, check the alignment of both sensors with the probe. The wires that connect the sensors to the
probe are very thin and bend easily. If this happens, correct the alignment by holding the sensor very
gently with a pair of small flat nosed pliers.
根据不同应用，清理过滤器的次数不同。清理过程不需要从探头上拿下。清理需要一个优质的刷子。如果
这样不能充分清理干净，则需要重新更换过滤器。如果更换则将此过滤器拿掉。在更换新的过滤器之前，
检查探头的温湿度传感器为对齐竖直。连接传感器到探头的丝非常细且容易弯。如果发生这种情况，用楔
型钳轻轻校正传感器。
